I loved this book when I was young. Like 16 years old or so. I am still very interested in things like formal systems and automated theorem proving and that started with this book. However, when I now look at the main idea of the book I fin

Not necessarily. I suspect the Poincare recurrence Theorem provides us with enormous durations, like 10^(number of dynamical variables), with the unit of time omitted because of utter irrelevance, or something even more horrific. It may be

There is an upper limit when so much energy is put in that it creates a black hole.

Sounds pretty good as such. The worry to have these days, though, is if we can also get this without energy usage data being traded between all sorts of shady companies and/or criminal organizations.

Entropy. Delta S = Delta Q / T. An efficient use of energy produces as little entropy as possible. Here the loss is Delta Q / 303 - Delta Q / 3043. T in Kelvin.

I prefer first thinking to immediately doing something. Especially in programming one can easily create an even bigger mess by picking a wrong direction. I tend to think about what the steps were that got me to the place where I got stuck a

"It seems the author indeed is not a SW Engineer". This is a pretty ridiculous notion if you just cursorily glance over the page. It is quite clear that this guy is more of a software engineer than most with that title will ever b

I started going to school all by myself, on bike, starting age 6 and did so reliably.

Meh, from a strict game theory perspective restricting trade makes both sides poorer. You know, both parties in a trading contract only sign on the dotted line if both are advantaged by it.

The problem is that an architecture is created that does not fit the problems that need to be solved. This is inevitable if lots of architecture is created before working on real requirements. TDD gets this right: start with actual requirem

I tried to go from 'Wernhout', which is the village I grew up in, to C++. Both have their wikipedia entries and also show up below the edit field when typing it in. Then it says 'Start page "Wernhout" does not exist

No. Or maybe only if you also consider 'village' and 'city' to be the same thing.

You mean an input device that has, like, 104 keys to rotate along 52 different axes?

"sanction the whole country to death because they don't agree with policies of people in power." 'Sanctioning to death' is perhaps not reasonable but, still, there should be standards for dealing with countries. Let

I agree with you. If those tool actually enforced good quality it would be one thing but what is actually being enforced is mediocrity and enforcing the power play of some individuals who have decided for all others what is good.

I went to a talk by Rob van Zeijst about the match of Lee Sedol and Alphago and he was saying that after move 37, the push along the fourth line would have been better for Lee Sedol. And also, move 78 should not have worked, or at least no

They do not really require it but note my other answer in this subthread.

Well, inductive constructions need positivity conditions to be consistent. These are complicated enough to suggest that they need to be proven instead of accepted as part of the formal system.

I did study HOL Light. Although it is very simple, I found parts of it to be a bit ugly. It treats the left of the turnstyle (|-) as a kind of set where you sometimes have to remove all alpha-equivalent terms. I.e., the DEDUCT_ANTISYM_RULE

Both really. Just as few givens as possible whether they are baked in or added on as axioms.

Well, I tried to have only one universe level but I found that I could not do some rather simple constructions without proof irrelevance. And that generally proof irrelevance seems to make quite a few things quite a bit easier, also requiri

I have a project to write a proof assistant that is as simple as possible while still usable. A kind of turing tar pit but for proofs instead of programs. Some early attempts did not quite work out. I try to get it off the ground using the

This is a very simplistic approach to simplicity. Simplicity is not just counting the number of characters you see. A function in a statically typed language may have a signature that says 'it takes an integer and returns an integer&#x

Well.... One still obtains pi for the ratio of circumference vs diameter in the limit that the diameter goes to zero.

It is not that I necessarily disagree with the author but it does seem like he is making it a bit too easy for himself to make his point. Ever since C++ got lambdas, I would say that bind should be considered deprecated. It is more difficul

It would appear to be a bit hard to target two outputs when you have one input....

If anyone would have taken the trouble of looking into it, it would probably be found pretty quickly but it is the kind of thing that is not a show stopper, so nobody really looked into it. Also, it now sounds trivial because I am giving aw

This kind of straight forward/naive code actually tends to contain many bugs. I once worked with a guy who very quickly produced stuff. One thing he wrote was a program to display a table on a small screen. He mentioned that he thought
